Lightroom histogram blank & zoomed image not properly formed

This problem occurs on certain images. In grid view the histogram is blank. In loupe view, histogram is still blank and zooming in to 100% gives a pixelated up-ressed image. Changing to develop module shows the histogram properly and the 100% zoom is fully resolved. Changing back to loupe view goes back to the pixelated up-ressed image again with the blank histogram.

Rebuilding previews or building smart previews or building 1:1 previews does not help.

By experimentation, the only solution I have found is to shut LR down and delete the preview file from disk. The problem reported above crops up after every second or third import from CF card, so I am frequently deleting all computed previews. It is a less than ideal situation.
